Specification of Letters Patent.

Patented Nov. 15, 1921.

Original application filed July 30, 1915, Serial No. 42,774. Renewed J'u1y17, 1919, Serial No. 311,689. Divided and this application filed December 12, 1919. Serial No. 344,419.

To all 10 h ome't may concern:

Be it known that I, J OHN D. Pnornsmv, a citizen of the United States, residing in Jackson, in the county of Lincoln and State of Wyoming, have invented certain new and useful Improvements in Firearms, of which the following is a specification.

This invention relates more especially to that class of firearms which are usually designated as small-arms, and a principal object of the invention is to furnish an improved magazine retaining and releasing device, or magazine-lock, particularly applicable to auto-loading and automatic pistols One class of small-arms to which my present improvements are applicable, includes the auto-loading pistols in whicha Ina-ga zine of tubular form, or cartridge carrier, is; removably secured within the grip, or handle-portion of the frame or receiver of the firearm. An improved auto-loadingpistol of this kind is described in my Patent No. 1,348,733, dated August 3, 1920, and granted on my copending application (renewal) Serial No. 311,689, filed July 17, 1919, and the improvements herein described and claimed are also illustrated in my said patent, but are not'cl'aimed therein. Tl ere fore, for convenience of illustration, I have herein illustrated my present improvements as arranged and applied tothe particular kind of auto-loading pistol which is shown in the drawings of said patent, to which reference may be had.

In the accompanying drawings forming a part of this specification, Figure'l is a side elevation of an auto-loading pistol furnished with my present improvements; this view is a left-hand sideview corresponding gener ally withthe left-hand side View shown in Fig. 1 of said patent. v

Similar charactersdesignate like parts in all the views.

My magazine-lock denoted generally by A, comprises a locking-portion m and a follower or locking-pin 13K The locking portion, m, is of cylindrical shell. form, and is 9, is a view of the lower end of said provided in its rear side with an inwardly. curvedor concave recess, 15, the purpose of which is to conform to and receive-the adacent edge of a removable cartridge receptacle or holder, such'as R, which edge is usually of a substantially convex form, and which receptacle or holder is insertible in the magazine chamber M. By "front and rear side, 'here and elsewhere herein, 1S meant the side of my magazine-lock as related to the frame or receiver B, toward the muzzle or toward the rear of the pistol of which such frame or receiver is a portion.

-1 The locking-portion m has a rearwardly hereinafter more fully described.

'By. outer and inner end, here and elsewhere herein is meant, the end of my magazine-lock as related to the right or left hand side of the frame or receiver B, of the pistol when the pistol is in firing position,

and of which is a portion.

The follower or locking-pin 13, comprises a cylindrical body-portion, 17, and a spring 13 The body-portion 17, is provided near its inner end with a flanged head .13. The spring 13 preferably is a helix spring and is arranged around the body-portion 17 inwardly of the flanged head 13, and bearing at one end upon the flanged head 13, the purpose of the spring 13 being hereinafter more fully described.

pistol such frame or. receiver Suitable intersecting holes or aperturest and 23*, Figs. 1 and 2, are formed in the frame or receiver B, of the pistol to hold the locking-portion m and the follower 13 in proper relation to each other, and also to prevent my magazine lock M from turning or revolving in the frame or receiver B, when the parts m and 13 are inserted in their respective holes and are in operative engagement.

To assemble the parts of my magazinelock the locking-portion m is inserted in the hole or orifice t from the outer or right hand side of the frame or receiver B, the outer end of the locking-portion m, being tilted forwardly relative to the frame or receiver B, so that the outer end of the concave recessed front side of the lockingportion m will lie in the path of the cylindrical body-portion 17, andthe inner end of the concave recessed front side of the locking-portion m, when the body-portion 17, is inserted in the hole or aperture 25 will lie out ofthe path of the body-pen tion 17. V

V The cylindrical body-portion 17 is inserted in the hole or aperture t from the inner or left, hand side of the frame or receiver B, and pushed inwardly until the right hand end of the spring 13 comes in contact with the interior surface, 18, of the frame or receiver B, the holes 23 and t being arranged toprovide for such contact. The other end of the spring 13 bears on the flanged head 13*, of the body-portion 17,

the pressure of the spring 13 being to thrustthe body-portion 17, toward the inner side or'left hand side of the frame or receiver B. ,The spring 13 when the locking-portion m, and the follower 13, are 7 locked together in operative relation being intended to holdthese parts in this relation, and also to permit the moving or pushing outwardly, or toward the right hand side of the frame or receiver B, of the locking-portion m and the follower 13, while locked together, to release the ledge 13 from engagement with the cartridgereceptacle or holder R, for the removal of such receptacle or holderfrom the magazine chamber M; and, when outward pressure on the locking-portion m and follower 13', is relieved to move the locking-portion and follower inwardly, or to the left, to reengage the ledge-13 with the cartridgereceptacle or holder R, to retain the same in the magazine chamber M, Figs. 3 and 4. The outer end of the locking-portion m, is then tilted toward the rear of the frame or receiver B, theconcave recessed front side of the locking-portion m, thus being partially engaged with the cylindrical body-portion 17, and the notchor recess 13, ofthe locking-portion m being substantially in line with. the flanged head 13', ofthe body-portion17, and snapping into engagement with the flanged head 13, mymagazihe-lockv assuming the position shown in Fig. 3.

The edges of the concave recessed front side of the locking-portion m, are inclined toward the rear of the frame or receiver B, 7,

to provide clearance for the spring 13 To insert a cartridge receptacle or holder, such as R, in the pistol my magazine-lock is pressed outwardly, or toward the right hand side of the frame or receiver B, and so held until the projection 0r ledge 13*, of the locking-portion m is drawn out of the path of the cartridge receptacle or holder as it is inserted in the magazine chamber of the pistol.

The cartridge receptacle or holder is pushed into the magazine chamber M, usually from the bottom thereof, upwardly, pressure of my magazinedock is released and as upward push on the carriage receptacle or holder is continuedthe projection or ledge 13, snaps intothe' recess or notch m 1n, the cartridge receptacle or holder, and thereby prevents upward or downward movement of the receptacle or holder, or unintentional removal thereof from the maga-t zine chamber of the pistol, Figs. 3, 4, 5, and 6.

To disassemble my magazine-lock, the.

same being in the position shown in Fig. v3, the magazine-lock is ushed outwardly, or

toward the right han side of the'frame or,

chamber, the magazine lock is then pushed.

farther inwardly until the ledge 13 is dis and the locking-portion mis withdrawn from the outer or right hand side ofthe frame or receiver B. r

I thus provlde a magazine-lock which may be assembled or disassembled by finger -man1pulat1on and entirely without the use of a tool.

The ex terior'surfaces .of the ends of my magazinelock may :be roughed or crosshatched for convenience of manipulation.
